"To all whom it may concern:

Be it known that I, EDWARD H. MoCLoUD, a citizen ofthe United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Metallic Doors, of which the followin is a specification.

The object of this invention is to provide a door or door member of simple and economical for'm, light in weight and durable in use.

The invention is embodied in the example herein shown and described, the features ofbeing finally claimed.

novelt lie accompanying drawings Int Figure 1 is a plan'vlew of the inner side of the door or door member. Fi 2 is a vertical section on the line II I Fig. 1 looking to the left.

with its four corners cut out as shown at 6' so that the piece can have its flanges or margins 7 all bent up in the same direction and upon the broken lines to form a cell or pan-like body as indicated in Fig. 5. After the margins are bent up as shown the end of the mar ins where they meetat the corners are wel ed or soldered together to complete the. cell or pan-like structure, as shown at 8.

If the door isto be used for fire protection the aforesaid margins are preferably welded together. In constructing the door or door member any suitable number of these cells orv pan-like bodies are placed margin to margin in one or more rows and riveted together by rivets as illustrated at 9 in Figs. 1, 2 and 3.

When two or more rows of the cells united by the rivets 9 are to be employedI inter- Specification of Letters .Patent.

or door member can be stiffened by riveting thereto angle bars 12, said last named bars being preferably of the same depth as the intermediate bars 10.

The vertical edges of the door or door member are shown to have riveted to them angle bars 13 projecting from the opposite or outer face of the door or door member and each of these has one of its webs standing inward over the face of the door as best seen in Fig. 3, said bars 13 thus serving not only to strengthen those edges but also to providezchannels or guides to receive and retain another sliding door member if desired.

The numerous webs formed by the cell margins aflord great strength against flexing the door without adding unduly to the weight thereof and the outer side of the door presents a neat, smooth and almost unbroken ap earance.

n the drawings I have illustrated a rather small door or door member but the cells or rowsof cells may be multiplied indefinitely according to the size required. I herein speak of a door or door member as indicat ing that the door may be composed of' a single structure like that shown or it may be composed of several of them. In the latter case the door members are also denominated as door sections.

The number,.fo rms and proportions of the parts can be changed or some parts omitted without departing from the g1st of the in.- vention as claimed.

What I claim is- 1. A door section'comprising, in combination a plurality of rows of flanged panlike c'ells,a reinforcing barlocated between I and secured to the flanges of the cells, reinforcing bars secured to the outer flanges of the rows of cells, said reinforcing bars combination, a plurality of horizontal rows of flanged pan-like cells, areinforcing bar located between and secured to the flanges of the cells, reinforcing bars secured along the outer horizontal flanges of the section and reinforcing and guiding bars secured on the vertical flanges, said last named bars projecting in a direction opposed to the direction of the ro'ection of the flan es.
